'ZEORGING ME CHAN'ISM.

My invention relates, to forging mechalsms, and more particularly toforging ,riechani'sm's of a type especially adapted for use Atheformation of channeler steels.

flnithe usual channeler gang there are provided steels which serve forthe purpose of r,and other steels `vv-hieh serve the .purpose 'ofleveling, the chopping steels projecting downward .slightly further thanthe vleveli'ng steels and having their 'edgesex ieeii'ding transverselyoi' the chahiieler, pracatrigditV ang-les V`to the path o I" iiioveijaeto' the :gang during operation. rlfhe leyeling steels have diagonallyarranged edges whichdo vriot project downward quite so Vfar as thechopping steels, hut which serve to level oli and loosen the ridges leftafter the passage of the choppingsteels. Various forms of dies havelloeen devised heretofore, but it has always heen vnecessary in theemployment of these dies for the sharpening of .channeler *steels toemploy several sets of ydies to secure the desired results, itordinarilyv beingA necessary to make a wholly distinctset for thediagonale from those y'used for the ordinary transverse or choppingsteels. s

1 An obg'ect of my invention lis to `provide improved forging mechanismfor tlie'shalp* ening of implements of the type employed in channelergangs. Another object of my iiiveiition is to pro-vide improved die.means whereby all lthe operations necessary` for the Aformation of boththe straight and diagonal steels which Ygo to makeup a coii'iplete:chan`eler gang may loe executed. @ther objects andk advantagesof myinvention'will hereii-ia'ffefire fairy appear.

'In the accompanying drawings I have shown 'for purposesloiillust-ration two forms which my 'invention may assume in Vpracticef Inthese drawings- Fig. 1 is a side elevation of thedie means provided forthe, purpose of flattening the tiiaiisverse vand diagonal isteels andltapering the former.

As it will in nowise increase the clarity of the disclosure to show thevforging mechanism with which my :improved dies are employechl have notvillustrated such machines and Yit will he understood that throughoutthe drawings of the forging dies vthe lower die is stationary, while theupper iiiately 45 degrees to vthe horizontal and, forof the Vertremityof the surface siga downwardly acing,vopposite ly sloping sur- :tace 5which makes aslight angle, herein 5 degrees, with the horizontal At itsright hand side, as viewed in Fig.c l, this die is provided withAflattening and lateral .edge forming inclined surfaces and 8respectively whichintersec't `at 9 andwhich are their line of'intersectionslightly rounded oli, for fullering action to initiallyVroughly reduce the-size of the steel har. The lateral edge formingmeanscomprising the surface 8 and the surfaces on the cooperating'blocks 28lor 35 is .for roughlyr gaging kthelateral edges the st eel, The lowerdie at its left hand side, as viewed vin Q,Mis provided with an.inclined surface 1 2 upon which `a e101 @au 1019er` :la -h ie and asurfe 5H v n a' @time eg@ d at??? dr es different form cutting edgeforming means for forming the cutting edge of a steel. Forwardly of thecutting off block 12 there is a vertical wall 17 which constitutes therear wall of a recess 18. rllhis recess has a bottom wall 19 and intothis recess there may be set, depending upon the desired, one or anotherof a series of gaging blocks 20, 21, 22 and 23 (see Fig. 5). The uppersurface of these gaging blocks is arranged to make with respect to thehorizontal an equal but opposite angle to the surface 5. At the otherside of the die block 2 there is another fiattening surface 26 which isoppositely inclined to the surface 7 and cooperates with that surface inthe drawing out and flattening of a channeler steel. The surface 26 iscarried up to a point opposite the fullering point 9 on the upper die land then slopes away for a short distance as at 27. A recess 28 isformed to the rear of the peint 2.7. The function of this recess willhereinafter be more fully describe-d. ln order to permit tapering thesides of the transverse steels, there may be used a block 28 whose topis oppositely sloped compared with the surface 8 to thereby allow thelateral edges of the steel to be formed, and which fits in the recess28, but this block is ordinarily unnecessary as the flattening of thetransverse steels seldom is such as to produce as great a width behindthe edges as at the latter.

The mode of operation of the dies as so far described is as follows: Ablank steel or a dull steel will be worked between the surfaces 7 and 26when in a properly heated condition, the steel, if extremely dull,having its forward portion projected beyond the portions 9 and 27 toobtain a fuller-ing action. After the steel has bee-n tapered to thedesired degree, a proper cutting edge is formed thereon by placing theextremity of the steel upon the edge 14 and causing the die 1 to strikethe steel a sharp blow. Thereby a proper cutting edge is produced. Tomake the steel of the proper gage, it is next turned on edge and, ifdesired, may be tapered between the surfaces 8 and block 28, or simplythe proper die block, 20-23, having been selected and placed inposition, the front end of the steel is rested upon the block 20, 21, 22or 23, which is in use, and the upper edge is struck by the surface 5,the dies being prevented by the portions 29 and 30 from coming togethercloser than the proper gage. The last operation will nearly alwayssuffice.

A diagonal steel will be flattened in a manner similar' to thatdescribed with reference to the flattening of the transverse steels.rlhe gaging, however, cannot be accomplished by the surface 5 and blockpreviously employed. I accordingly have pro vided an attachment 35adapted to fit in the recess 28 and providing at 31 an inclined surfaceadapted to support the lateral inclined surface of the diagonal steeland further providing as at 32 an overlying portion or lip adapted tocatch the lower side of the diagonal steel and irevent twisting thereofas the upper side is struck by the surface 8. lt will be noted that thisloose piece is provided with recesses 33 which may be seated over pins34 to hold the loose piece in position, the block 28 being obviouslysimilarly held. As the angle ofthe surface S is not'less than the taperof the transverse steels, it will be understood that the diagonalsteels, when placed in the gang u with the transverse steels, will be ofthe proper gage, it being understood further that the distance betweenthe bottom of the recess in which the diagonal steel is received and themost remote point by which that steel can be engaged on the surface 8 isequal, when projected on a vertical plane, to the gage of a transversesteel. lt will be understood that the diagonal steel having beenflattened to the desired taper by the surfaces 7 and 26, may be restedupon the surface 31 and with its lower'edge caught under the lip 32 andthen struck by the surface 8 to produce the proper gage. Suitableclamping dies 39, of which one is shown in Figure 7, may grasp thediagonal steel and hold the same while a dolly tOhaving a diagonallyarranged groove stl for the purpose of sharpening the diagonal steels isused.

In the form of my invention shown in Figure 6, instead of cutting awaythe lower die and forming a recess 28 and using the loose piece 35, thelower die'is made to correspond in shape to the upper die at its righthand side and when the gaging operation is to be performed on diagonalsteels,

the mechanism including the parts 31, 32,

etc. is mounted by means of a saddle-like support 42 upon the lowerblock 2. The mode of opera-tion of this form of my in vention is thesame as in the preceding cases.
